Hello everyone, a friend got a large Magnum Phoenix GS CNC Servo system router probably built in the 1990’s, it came from a shop that went out business years ago. The machine, visually looks in good condition, he only tested the big vacuum motor. The router it is somewhat connected thru the serial port (many wires not connected at all) to an old taken apart computer with a Pentium II cpu. Looking at its hard drive, the programs that were been used to run it (DOS environment) were CNC7 and Procad. My question is, to replace the electronics / controllers to be able to run it connecting to a new pc, (using a USB port or Parallel port if needed), would it be too expensive? Is it worth? Is there anyone you can recommend to look at it, the router is in South Florida, thank you for your help.
